@mjgardner There is a conscious attempt to get rid of #Rlang and the script is highly reminiscent of #perl. The push for #Python is kind of nuts given that the language is kinda slow and it shines only because of certain libraries written in #clang.
Going back to #perl, I will reiterate the same points I 've made in other fora: it needs a strong type system as an ad-on, a tabular data type that is more space efficient than an array of arrays to adapt to our #bigdata era.
